Hi Team,

We are planning to upgrade the DPDK stable LTS version from DPDK19.11.
Could you please suggest what would be the stable LTS version of DPDK ?

Thanks,
Kamaraj

If you are looking for an LTS version that will be maintained for the 
longest time in the future, then you can jump to the latest DPDK LTS 
series 21.11.

It will be maintained with backported bugfixes until at least November 
2023, but we are trialing longer support on some LTS releases so there 
is a possibility it might be extended.

If you take a look at http://core.dpdk.org/roadmap/#stable you can see 
the current roadmap of how long each LTS version is maintained for.

thanks,
Kevin.

Thanks Kevin.

Apart from release notes to identify changes of DPDK version from 19.11 to
21.11, is there any any major design changes in DPDK ? for example (memory
management, mempool allocation behavior etc)
Please share if there is any pointers.

Thanks,
Kamaraj

Notably the make based build system was removed in 20.11, but you'll 
need to check the release notes [0] to see what else impacts you. In 
particular the 20.11 and 21.11 were ABI breaking releases.
